Well, if you need it, you need it, like I said that's up to you and your doc. Personally, I'm of the persuasion that if I can get by without someting then I am by no means going to take it. I figure I've already got enough stuff flowing through my veins when on a cycle, and when I come off a cycle I come off everything. Minus taking a good multi, when off cycle I don't take anything, i.e. pain killers, any OTC meds, nothing. I just like the idea of letting my body clear out from any unnecessary substances.
